"A female witness saw two middle-eastern running away toward the stadium immediately after the explosion."
Another interesting detail that I haven't seen before. Where did you learn this?
Way back on the 3000+ thread, probably prior to #1500, but I don't care to go back looking for it.
You should read the main thread:

The information is from a post by PhiKapMom last night. She is not the one who actualy saw this though. Search her posts from last night.
See the posts by PhiKapMom on the other thread.
I didn't see anything except hear the bomb explode. Afterwards at my son's fraternity a girl from Iran was explaining what she saw and my understanding is that she has been interviewed at some length but I have no further details.
